You can expand and simplify the expansion under the square root.
And you were asked to apply implicit differentiation. How would you do it?

@iwantcalculus, there's the "brute force" way, which is how you are proceeding, and there's a different way that involves implicit differentiation. What's another way to write the equation you're starting with.
